Abstract This article outlines Locke's theory of war as found in his political writings and seeks to redress a perceived imbalance in John Locke's morality of war. Locke's strident rejection of any sense of proportionality in warfare against unjust aggression, as read in the Second Treatise of Government, has to be tempered with his general philosophical programme against extremism of any sort. Arguably, Locke's war ethic when read alone is strict, objective, and emphatic, but when compared with his epistemological work, its righteousness is reduced to extreme circumstances
